TO. ALL WH OM IT MAY CONGERN:

Be it lcnownthat I, WILLIAM S. MEAD, of New York, in the county and State of New York, have invented a nen and improved Mechanical Motion; and I do hereby declare that the following is a Iull, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying` drawing, forming part of this specification, in whichdrawiug Figure I represents a sectional side elevation of this invention. Figure 2 is a plan or top view of the same. Similar letters indicate corresponding parts.

This invention relates to anrapparatus composed cfa ily-wheeler other equivalent body, which ismountod 1 on a crank-shaft that has its bearings in two rockers, and the crank-pins of `whichconnect by suitable-links with the fixed frame of the apparatus in such a manner that by imparting a revolving motion to said crank-shaft a double motion is imparted to thc ily-wheel or other body mounted on said shaft, viz, a revolving inotinandvi an oscillating motion, and the double momentum of the revolving and of the oscillating motion is made'avalable to overcome the resistance of a sawor other working machine, while at thcsame timcthe necessitylofraisng the weight ofv the fly-wheel or other equivalent body is avoided. The` motion is transmitted to the saw or other working,l machine by one or more cennecting-rods extending from the iiy-wheel Vshaft to a frame, which is suspended at one end, and connected at its other to the saw o1- other device in such a mannerlthat by imparting o, .j

revolving motion to the fly-wheel shaft an oscillating motion is imparted to the` saw or other device, and the momentum derived from the oscillating motion of the ily-wheel or other heavy body assists materially in overcoming the resistance of said saw or other working machine. The whole device is, mounted oniafranie provided with a wheel and han dles,`so that it can be readily moved from place to place. .i i A represents a frame made of wood, or any other suitable material, and supported by four (more or less) lcgsB. This frame is furnished at one end with a wheel, C, and at the opposite end with handles D, so thatit can Vbe readily and conveniently moved from place to place. v The legs B extend above the frame A, so `as `to forni a derrick, E, and the lower part of said frame forms the hearings for the shaft F, from whimeh extendt-he roclcing-armsG, andthese arms forrn the bearings for the main shaft AII,`,on which is mounteddthe ily-wheel or` other equivalent body I. The ends of the shaft H extend through the rocking-arms G, and on them are mounted the cranks a, the wristpins of which connect by links b with the clerricl; E, or with anyothcr ixed` pal-tof the main frame. A handle orwinch, c, serves to impart to the shaft H a revolving motion, and as said shaft revolves the arms G assume a rocking motion by the action of the cranks a and links `b, and atwofold eiiect of the momentum of the iiy-wheel or other equivalent body mount-eden sai'd shaft is obtained, first, from therevolving, and` second from the rocking motion .of said ily-wheel or other body. Inl order toapply` the motion ofthe-shaft H to some useful purpose, I suspend from the top of the derrick E a pendulum frame, J, which connects by one or more pitman-rods d with the shaft II, and to the lower ends of the pendulum `frame I connect one or more saws K, or any other device Vto which motion is to be imparted. Itwill `be readily understood that changing the point oi' connection between the pitlnan-rods d closer to or further from the point of suspension of the pendulum frame the stroke of the saw or saws can be increased or diminished at pleasure. Thesaws are connected to the pendulum frame by pivotsf, and from their b ack ends extend spi1alspringsg,`so that the teeth` the saw arehcld in contact with the wood or other material to-be cut. Ii' the machine is' to be uscdfor cutting;

'iirewood the sticks of woo'd are placed in a triangulaitrough and held in position by a suitableleren-catch.`

The ily-wheel, I, cnn be replaced by a grinding-stone, and if it is desired to usc this stone the links b are detached from the derrick or from the wrist-pins oi the cranks a, and the pendulum frame is secured by a stop, k.` By

ythese means the shaft H is brought in such a position that by means of thehandle or winch e arevolving :notion can be imparted to the grinding-stone in the same manner as to a stone mcun tedio the usual manner. If. desired, a treadle can be applied instead of the winch. v

From the above description the various advantages of my mechanical motion. wili bercadily understood, and require no further explanation. It' desired, a churn may be so applied that it can be operated 'fronrone of the cranks a. I disclaim everything shown and described in the patents of M. Kaefer May 31,1859, and March 5, 1860. r What I'clainnus new, and desire tesecurc by Letters Patent, is u The combination and arrangement of the wheel @,frameA, handles D, rocking-arms G, flywheel, or other equivalent body, I, links b, pitman-rods d, pendulum frame J, and saws K, all constructed and operating substantially as and for the purpose described.
